Thank you for the thorough bug report.
Indeed there's a problem.
We are looking at it.

Just a note though: the new iOS 14 icons are not supported yet...

[teras]

Current Git repository is able to load the IB file. It's still missing a few bits.
If you are still interested, we can pack a version and let you check it.
